Feasibility study After studying the new system plans, you have to check if it is possible to create the new system by looking at these options
Technically feasible - is the new system technically possible to implement in the time available?
Economically viable - will the cost of the new system be offset by savings once it is implemented, for example will it save the organisation time, money or increase its performance?
The project will only continue to the next stage if the answer to both of these questions is yes. At this point the decision makers in the organisation make the decision Top down Design Top down Design is a drawing technique used as part of the design stage in the Systems Life Cycle. A top down design is a technique that starts with the highest level of an idea and works its way down to the lowest level of detail. It shows the development of a new system, broken down into small logical 'chunks' of work. Each small 'chunk' will represent a complete section of work. The diagram will show the order in which work needs to be completed.
Analysis Stage: 1) Fact Finding/collecting data from the current system This method includes observation of how the current system works, who uses it, how efficient it is. Ways of collecting data are giving out questionnaires, interviewing people and looking at existing paper work 2) Description of the current system- establishing the inputs, outputs and processing being done.
How it works, its efficiency the time tables of it and how user friendly it is.
3) Identification of the problems with the current system
Conducting interviews with people who have used the current system and what could be improved. As well as giving questionnaires about people’s opinions and belief about the current system.
4) Agreeing the objectives with the customer
At this stage the employee and the customer have to agree on what the objectives of the system or business is.
5) Identifying and agreeing the customer’s requirements
At this stage the employee must be able to identify what the customers’ expectations and demands are from the business.
6) Interpreting the customer’s requirements
At this stage you would need to find out exactly what the customer needs and wants from the system.
7) Producing a cost-benefit analysis
At this stage you would need to determine the costs of the system and the benefits that would come out from the system and if it’s worth going ahead to do it.
8) Producing a data flow diagram Data flow diagram is a significant modeling technique for analyzing and constructing information processes.
